My planer doesn't do picky finish work, it's here to remove material and get on with it. Yes, Delignit dulls steel blades, but so does rock maple. Neither has nicked a blade that I've seen, though I have hit buried nasties and nicked them. I have a back beveled blade set I use when I'm planing the Delignit, and maple, and a normally sharpened set for spruce. If I'm doing a bunch of maple or spruce, I'll put in the appropriate blade set. Otherwise, whichever is in there gets used as is. Even planing the Delignit with the normally sharpened set doesn't do them significant damage for what I'm doing. Now I do have a significant edge fetish, and all my chisels and knives are kept quite sharp, but the planer is apparently outside that particular obsession for me. Ron N
